I have to a limited extent - I've been able to get the title of the modal and click the cancel or continue button (that's all I've needed to do) but it took me a while to get the xpath right to hook into the elements. Can you describe what you are trying to do?

I have a scenario where when we login with temporary password, a modal dialog box appears asking to reset the temporary password. When i try to automate the scenario my script is unable to identify the web elements in the dialog box which has 3 text boxes, two button Update Password and Cancel.

i have tried various ways like:

1) driver.switchTo().defaultContent(); -- to switch to the modal dialog box
